Dame’s Rocket

posted in: Plants, The Garden 2021 | 7

Do you have Dame’s Rocket in your garden? and do you mistakenly call it phlox? I thought we had wild phlox but after lots of reaching and searching of garden books and the internet it was discovered that we have Dame’s Rocket.

The most distinguishing feature between the two is that Dame’s Rocket has 4 petal flowers and phlox has 5 petals. So get out there and start counting those petals.

Dame’s Rocket is a completely different flower family. It is Hesperis matronalis, a member of the mustard family, but it resembles phlox in height and colour, which can be white, pink or mauve. The flower stalks can be up to 1 metre tall.

Above shows the green growth at the beginning of May. It has really spread since last year and can be considered an invasive species. The blooms appear towards the end of May and the beginning of June.

Last year the hummingbird clear wing moth loved visiting the Dame’s Rocket blooms.

I’m waiting for the flowers to appear towards the end of the month.

    It’s a very pretty flower but I haven’t got either that or phlox in my garden, I have a feeling I may have seen it in the wild though I’ll have to keep a look out for it, the pollinators certainly love it.

    I don’t think we have any unless some come up in the front garden as Al only widened that garden. It is very pretty and sure looks like Phlox.

    I see lots of this along roadsides, and down by the swamp (well, before they clear-cut it for sewer pipes). I always thought it was phlox, didn’t know the difference! Next time I see some, I will count petals!
