Bring On The Fall Color

Gingko 'Troll' The Fall colors seem to be coming sooner this year. The Stewartia was the first tree I noticed, and it changed weeks ago. Others, such as many of the Japanese maples and dogwoods, haven't changed yet. Stewartia pseudocamellia Bluestar ( Amsonia hubrechtii) is the most colorful fall perennial. I would say the most colorful shrub is the Bloodtwig Dogwood ( Cornus 'Midwinter Fire'). It began to change color weeks ago and it has really grown this year.  The best year so far for Fothergilla 'Jane Platt'. This has been an extreme slow grower but it is finally filling in. A colorful grouping with the amazing Miscanthus 'Little Miss',  Joe Pye Weed and Sourwood ( Oxydendrum arboretum ).  Miscanthus 'Little Miss' is the most colorful ornamental grass in the garden. Black Tupelo ( Nyssa sylvatica ) changes color from the inside out. Wiegela 'Wings of Fire' Looking down the garden pathway with Cornus 'Midwinter Fire'

Badja Peak Mint Bush


Every time we have a garden tour, there seems to be one plant that people single out and ask about. This time, it was  Prostanthera cuneata 'Badja Peak', commonly referred to as "Alpine Bush Mint" or "Australian Bush Mint" (originating from Alpine regions of Australia).

This small shrub was planted in July of 2021 so this is its second year (I mistakenly told someone it had been here three years - sorry!) It is located in the front garden on the northeast side and has survived two winters. Most references recommend planting it in a warm, sheltered spot but this isn't really the case in our garden. It is listed as being hardy to 10-15 degrees.

Our plant gets considerable shade with periods of full sun around mid-day and some afternoon sun but I would say it gets more shade than sun. This year it is about 2 feet tall and 4 feet wide with a somewhat sprawling habit. The evergreen foliage is dark green and minty aromatic when crushed. Flowers began to appear in late May. The flowers are large, cupped and white with purple flecks inside the flower. Very pretty!

    I hope you had a successful open garden: I wish you lived closer to Seattle so I could visit. This "Australian Bush Mint" is lovely (evergreens brighten the spirit in winter) and vigorous: 4' wide in 2 years! What's it's supposed eventual size?

      We had around 85 people I think. It was super busy and a nice pleasant day for it. It can get anywhere from 3-5 feet from what I've read.

    I love the way Australian Bush Mint surrounds your bird bath. So pretty!

    Thank you for the introduction to this interesting plant, Phillip. I grow Prostanthera ovalifolia 'Variegata" (also called mint bush) but I'd never heard of this one. Mine produces small lavender blooms, although before this year they've bloomed lightly, if at all. (I'll once again attribute the difference this year to our heavier rain.) I'll be on the lookout for your species.

    That's a beauty. The flowers are quite something. It looks very happy in your garden.

    "Alpine" doesn't usually come to mind when paired with "Australia", but of course there's more to Australia than arid regions and sandy beaches.

    Those blooms look like small orchids. Are they fragrant? They remind me of Catalpa tree blooms.
