Leaves that Beat the Heat (and the Deer)

Now those of you in Texas and Florida will laugh – but it is HOT here in Seattle. And by that I mean mid-high 80’s for a few weeks now with just two days of torrential rain somewhere in the middle. I know it’s all relative but the people – and plants that live in Seattle aren’t used to such extended periods of heat and drought.

This is therefore the perfect time to assess which are the foliage workhorses in the garden. What still looks not only good but GREAT, is healthy, doesn’t need fussing with and has barely been given a drop of extra water? We expect grasses and succulents to be drought tolerant but what else is there?

Most trees and conifers are fine by virtue of their deep root system so I’ll keep this to my top shrubs, perennials and annuals that I grow for their leafy lusciousness – and deer tolerance.

Here are the awards;

Best Combo

It may look delicate but this combo is TOUGH!

It may look delicate but this combo is TOUGH!

This is an amazing trio; the perennial Arkansas bluestar (Amsonia hubrechtii) gives height (and turns orange in fall) while two annuals – the chartreuse Lemon Fizz cotton lavender (Santolina virens ‘Lemon Fizz’) and silver licorice plant (Helichrysum ‘Petit Licorice’) form a fuzzy groundcover. I can’t reach them with a hosepipe so they are truly on their own and they look fantastic. I was a little concerned after our two day downpour which left the Arkansas bluestar flattened but 24 hours later when I ventured out with sticks and string they had picked themselves right back up and needed no help from me at all.

Best Bling

Silver Mound wormwood (Artemisia schmidtiana ‘Nana’) is much tougher than the fine textured foliage would suggest. In fact this fluffy perennial prefers tough love and will quickly rot with too much love, water or fertilizer. It dies down in winter and can be a bit slow to reappear in spring but it’s worth waiting for. This 2′ silver mound will add some glitz to the border like no other plant can.

Best Variegated Leaf

Not your typical barberry

Not your typical barberry

I’m partial to barberries. They come in lots of different shapes, sizes and colors, are drought resistant, deer resistant and rabbit resistant. Usually.

Thankfully they are NOT invasive in the Seattle area. If they are a problem in your state I’ll forgive you for skipping over this bit.

Lime Glow barberry is the pretty little sister of Rose Glow. Marbled light green and creamy white leaves with pale peach new growth and stems makes this a rather romantic addition to the garden border. It seems to be much slower growing than Rose Glow so enjoy this in containers as well as the landscape.

I have two of these. The first one is out of reach of the hosepipe so is on a ‘do or die’ regime. It is ‘doing’. The second was unceremoniously dug up one blisteringly hot day and relocated, watered a couple of times then forgotten about. Much to my surprise it is not only still alive it still has all its leaves. Pretty impressive as well as pretty.

Best Native

A bronze beauty – Northern bush honeysuckle

If you thought native plants were boring this one will change your mind. Northern bush honeysuckle (Diervilla lonicera) grows in sun or shade, wet soil or dry, has fragrant blooms and beautiful fall color. I have one in sun and one in shade. The shaded one is mostly green but the one in full sun (above) remains bronze for much of the year which I love. Bambi has ignored both plants except for a tiny nibble on the new growth of one stem. Thankfully it wasn’t to his taste. (or he was full by then).

Best Surprise

Glossy abelia - worth a second look

Glossy abelia – worth a second look

I have a low hedge of glossy abelia (Abelia x grandiflora) at the side of our cabin. I don’t water them, fertilize them or talk to them. In fact I forget they are there until I become aware of a hummingbird frenzy in that part of the garden as the fragrant white flowers are a magnet for them it seems.

This unassuming shrub is one of the unsung heroes of my garden. It is usually evergreen, has healthy, glossy green leaves which tint red in fall and rich burgundy stems. While the flowers are white the sepals are pink giving a lovely two tone effect and the flowers last well into November.

I have not watered this for three years and the deer haven’t even tested it. I trimmed the height a bit this year but that is the extent of the care I have given it.

After this hot, dry stretch it is not only looking good it is thriving. Quite the surprise

    Summer drought is normal here in Seattle. Summer heat is not. The torrential rain was a welcome surprise.

    I live in east TN so summer heat and humidity are a given and it’s often the humidity that proves to be the most challenging variable to deal with. I particularly perked up at your mention of the abelia and what a good serving soldier it is. I have had no experience with abelia until recently when I bought a newish variety called ‘Rose Creek’ to use in a container arrangement. I hope it proves to be a survivor and I would like to put it in the ground this fall. Do you have an opinion about ‘Rose Creek’ and how it compares to the one you praised in your post?

      I haven’t heard of that abelia so I’ll be interested to see how it fares. I have grown a few of the newer, fancier ones such as Kaleidoscope which I love for the color. However this basic glossy abelia beats them on staying power. Frances mason is another good one.
