Gardeners' Notes:

Wonderful plant for me in its fourth season now, originally wintersown in milk jugs and transplanted into the garden as a tiny seedling. A scrawny thing in its second year, still lanky but flowering in its third, now filling out and taking up quite a lot of space in its fourth.

I have these in a "hell strip" location where the height needs to stay low enough for visibility when backing out of the driveway. The foliage stays under two feet, with flowering stems less than three feet, so it works for me.

It does get quite wide, though. If you have lower things that don't mind some shade, they could be closer to the stems but underneath the foliage. The six I have really dominate the bed now, so I will be removing 3-4 of them so that the others can shine more as s... read more

Love this plant - it's such a nice compact size, the folige is an interesting blueish grey/green, and it's tough as nails. Mine grows in clay with minimal to no watering, even in 100+ degree weather when it doesn't rain for 3 weeks at a time. I love that it requires no staking and is small and airy enough to fit almost anywhere. My oly complaint is that the gorgeous flowers don't last very long - 3 weeks at most.

Have this in a part sun location and it does well, also mine gets 3-4 feet high.

This is a great plant of very useful habit. I wish breeders would use this to produce new hybrids instead of the big ones hitting the market. A 5' wide perennial is something harder to use. This one is however perfect for a perennial in the everyday landscape. You cant go wrong and it is native plus interesting.

I finally saw a similar variety of this the other day and was able to look this 'mystery' plant of mine up. I bought a toad lily about 4-5 years ago and a stem of this was in the pot.

It finally bloomed for the first time this season and I thought it was just gorgeous. I love the silvery gray foilage too. Considering that it was in a shade plant pot growing....I have had in on the East side of the house this whole time, not knowing that it was tolerable of full sun. Thanks for the information folks.

A strikingly beautiful plant. It takes a year or two to establish, but is practically indestructible after that. B australis var. minor makes, in many ways, a better garden plant than the typical B. australis. It is more wind resistant, more drought tolerant, and less likely to overwhelm its neighboring plants than B. australis, for example.

Beautiful vase-shaped plant. The blue-green foliage is clean and attractive all season long. The flowers make good cut flowers. If grown in 100% full sun, it requires no staking; if planted too close to trees or any structure, it will lean away from it and require staking up. Long-lived and never requires division. Absolutely no maintenance!
