Other Uses

The branches have been used to make brooms[257].

Cultivation details

Tolerates most soils[200], but prefers a good loamy soil, abundant moisture and full sunlight[11, 200]. Prefers a moist lime-free soil[182], plants quickly become chlorotic on chalk soils[200]. A very cold hardy plant, tolerating temperatures down to about -25°c[200]. Hybridizes freely with other members of this genus[11]. A rampant suckering shrub, it quickly produces dense thickets and can be used for large-scale naturalistic plantings[200]. It is apt to get thin and poor unless divided up fairly regularly and replanted in fairly good soil[1].

Propagation

Seed - we have no information for this species but suggest sowing the seed as soon as it is ripe in a cold frame if possible. It is likely to require stratification before it germinates, so stored seed should be sown in a cold frame as early in the year as you receive it. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on in a cold frame for their first winter. Plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood, July/August in a light sandy soil a frame. Cuttings of mature wood of the current seasons growth, 15cm long, October/November in an outdoor frame[200]. Another report says that September is a good time to do this[11]. Division of suckers in early spring[200]. They can be planted out straight into their permanent positions.

I was looking for some detail re.my Spiraea Douglasii, and seeking to propagate it. After trying various of the websites that came up when I put the plant's name into a search engine, I tried yours (ie.one of the "results" of the search) which was much the most helpful. Thanks!

PS: I live in England, and although my Spiraea D. may not be as large as in the USA (where everything seems to be larger than here!!) it is certainly growing OK. From recollection it has come with me from my last two homes [or rather, the gardens of those homes], so it has endured moving also. I looked at the (old) packet recently and found that it was bought when the shop (not a garden centre) was selling certain plants off cheaply!

PS: I live in Essex, and although my Spiraea D. may not be as large as I have seen pictures of some in the USA (where everything seems to be larger than here!!) it is certainly growing OK. From recollection it has come with me from my last two homes [or rather, the gardens of those homes], so it has endured moving also. I looked at the (old) packet recently and found that it was bought when the shop (not a proper garden centre) was selling certain plants off cheaply! (I altered this note after pressing "confirm", so it may be partly duplicated - sorry!)
