Looking to Bring in Some Color This Spring with Perennials?

 
Perennials bring in the spring color like no other plants and can last for months and months and sometimes bloom more than once. These are great options for sunny areas of the yard. 

  • Alstromeria- comes in a varity of colors. It is great for clipping and putting in vases and lasts for up to two weeks.
  • Catmint- love the purple flowers that provide a cottage garden feel.  It is great contrast with white roses
  • Cornflowers- it is a striking looking flower to enjoy
  • Coreopsis- daisy like flower in lots of great colors
  • Forget Me Nots- classic with petite flowers. 
  • Gaura- a great white punch for the garden and the butterflies love it.
  • Rudebeckia- summer color with its “sun flower like” flower
  • Heuchera- it seems like every year they are coming out with a new variety. They are known for their interesting leaves.  I like to use them in containers with other plants too.
  • Lavender- lots of great varieties. One of my favorite classic looking french lavenders that doesn’t get so big and woody is the Hicote Lavender.
  • Jerusalem Sage- this is a new favorite of mine.  The yellow flower is very cool looking and the foliage looks good year around.
  • Yarrow- they have been expanding the flower color options.  The most common one is yellow in color
  • Penstomen- love this plant and blooms for months and usually twice in the season.  There are lots of colors to choose from especially in the pinks and purples
  • Salvia- lots of varieties and colors to choose from for your garden and very low maintenance.

Come to the Dark Side- Deep, Richly Colored Foliage Brings Drama to a Garden

Some of my favorite gardens are the ones that weave in dark colors to add a layer of complexity to the garden. Your eyes gravitate to the dark colors to see what they look like.  It helps to bring depth and texture to the garden


What we call “black” in the garden is actually shades of deep red, purple, brown and bronze.  When using black plants, opening up your color palett
What we call “black” in the garden is actually shades of deep red, purple, brown and bronze.  When using black plants, opening up your color palette is a must.  Green is the default color for foliage, so when incorporating black plants, it’s important to give thought to smoothly transitioning from the greens of most plants to the darkness of your garden star attraction.  Some color pairings make the task easier than others. Here are options that offer plenty of contrast without ever looking over done.

Black and Blue- Adding a splash of black foliage to blue flowers gives a nice punch.  Most black leaves have undertones of blue and purple in them so they compliment each other.  A good example of this is a blue/ purple penstomen, black colored heuchera, and purple lobelia .

Black and Silver- This is a moody combination that is stylish and modern.  Gray shines in gardens and looks great when mingled with darker leaves.  Amazing red phorium, Jerusalem sage and lavender is striking in a garden.

Black and White- We all love to wear it and it’s always in fashion so why not try it in the garden.  This is a high contrast power couple that makes the white pop.  I think mixing in some green is important with this combination too.  I have used this most often in potted plants for interesting table or side table color. I have in my garden in a shady area a combination of the Laceleaf Japanese Maple in ‘Ever Red’, oak hydrangeas and lopopetalum ‘razzleberri’. The loropetalum’razzleberri’ has green leaves with a touch of red at the tips which provides a nice transition from the deep red in the maple to white in the hydrangea.

Black and Chartreuse- This can be very striking in potted plants for annual color and fun to experiment.  I have tried it in combination with other colors too.  Both colors are striking so you need to use them both sparingly.
It is important not over do it with black plants. Decide on a few starring attractions, then surround them with supporting cast. Most black plants need light to look their best or they also get lost in the absence of light.

Time to Revamp Your Container Designs?

A great way to spruce up your patio is to update your containers.  I am definitely feeling the need to tackle a few of my containers.  It is important to set up your containers for success.

Begin with choosing the plant that will be your focal point, such as a dwarf tree, shrub or grass.  Evergreen plants look better all four seasons. Dwarf trees and shrubs work well because they are compact, slow growing and lend themselves to pruning. Dwarf conifers are a great option for more formal gardens and very low maintenance  You need to think through the amount of sun in the location of the container and if the plants can handle this amount of sun. Next select your perennials or annuals to compliment your focal point. Many perennials can take over the container so keep this in mind. You can cluster containers and have the focal point in one container and perennials and annuals in the other containers.

You have heard me before about the importance of soil but I will continue my mantra and encourage you to spend a few extra dollars for high quality planting soil.  Opt for potting mixes that get their nutrients from compost instead of synthetic fertilizer that has nitrogen and will accelerate growth causing over crowding.  Make sure not to fill the container to the brim with soil and leave 1-2 inches.  This allows water to soak in gradually and prevents overflowing.

Root competition is the most overlooked threat to potted plants.  If you have a plant that did not thrive last year you might consider trimming its roots. You need to prune their roots every two years.  To prune the roots moisten the soil and lay the container on its side to slide out the root ball of your dormant plant.  Use a small root pruning saw, pruners or gardening knife to sheer off roughly a third of the root ball. Repot the plant using fresh potting soil.

It is important to water and fertilize regularly to keep plants alive and healthy.  Drip for container plants is optimal but not always easy to set up.  It is a great excuse to get in your garden and enjoy it.  Have fun being creative with your containers.  It is hard for me to recommend plants without assessing the situation. Sunset online has lots of great ideas you can explore for inspiration.

March Gardening Punch List

Adapted from SFGate:

  • Finish planting bare-root plants in the garden. They should be planted before they begin to leaf out with the warming weather.
  • Finish pruning deciduous dormant plants such as fruit trees, grapes and cane berries before they leaf out. Prune fuchsias at the end of this month, leaving two swelling leaf buds on each pruned branch.
  • Fertilize roses when they begin to leaf out. Fertilize camellias, azaleas and rhododendron with an acid fertilizer.
  • Fertilize citrus trees with a high-nitrogen fertilizer that includes iron. An iron deficiency produces chlorosis, which manifests as yellowing leaves (with green veins) and is frequently observed in Bay Area citrus.
  • Fertilize bluegrass, fescue and rye lawns lightly with lawn fertilizer.
  • Shape up uneven azalea growth after the azaleas finish blooming.
  • Discard the spent blooms of withered rhododendron flowers, taking care not to injure the growth just below the flower.
  • Let daffodil bulbs recharge by leaving the leaves attached to the bulb to provide nourishment for next year's bloom. Let foliage wither and yellow.
  • Weed now before their roots get strong or, worse, they set seed. Dig out bulb-forming weeds such as oxalis and nutsedge.
  • Pest control means eliminating snails and slugs now before they damage plants.
  • Annual labors of love include planting annuals such as ageratum, cosmos, impatiens, lobelia, marigold, pansies, petunias and violas. You can mix them in with the perennials to extend the blooming period. Plant perennials such as achillea, campanulas, columbine, geranium and marguerites. Plant summer bulbs such as gladiolus, dahlias and lilies. Begonias from bulbs are also planted now.
