This happened to mine when it got too wet (leaking waterbutt). I gave it a Chelsea Chop and it got lots of healthy new growth. It flowered later as a result... in fact it only just finished at the end of October. So I vote for yours being too wet. Hope that helps.

Hi, Louise,
Generally, Perovskia don't need much water - they are pretty drought tolerant once established. Sounds like it is in the right place with the right type of soil. How yellow are the leaves? Are they dropping? Any chance you would be able to post a photo?

Perovskia 'Blue Spire' - Leaves at bottom going yellow

Question from Louise B

In forum: Pests, diseases and invasive biosecurity risks

I've had a quick look on Google and could only find two replies to this problem - one said it was too much water and one said it was not enough so I'm confused.
I have mine in a hot sunny south facing spot in gritty sandy soil with added gravel on top. I have had the sprinkler on a few evenings lately but it's also very dry out there so I'm really not sure.
Would appreciate advice!
Thanks
Louise

Evergreen shrubs

Message from Kathy C

In forum: Garden design

Hi, Lawrence,
A tall order to fill since it is tough to find an evergreen shrub that flowers that long and no t pink or red, but I think I have some ideas:
- Escallonia 'Iveyi' is evergreen, gets to be about 2-3m high with arching stems, glossy leaves, and white flowers in summer (I think this is my favourite from the list).
- Carpenteria californica - evergreen with dark green leaves and white flowers in summer - a bit tender so would be good in a sheltered spot along a fence.

- Coronilla valentina subsp. glauca - bushy, evergreen, yellow flowers in summer.
- Perovskia 'Blue Spire' - lovely grey-green foliage and upright stems with violet-blue flowers. Can be treated like a shrub or a perennial.
-Leptospermum
- Olearia macrodonta
- Philadelphus, perhaps the cultivar 'Virginal' - lovely semi-double white flowers in summer.
- Spiraea nipponica 'Snowmound'
So, just a few ideas....you can do a search on this site under the tab 'Plants' and then choose 'Select'. Once there, click on Advanced Search and you can choose all the attributes you want the plant to have.
Happy choosing and please let me know what you decide to plant!
