V few if any of the original 1850s giant sequoia are still alive (poss a couple in Scotland). Many were planted in the late 19th to early 20th C and they're v popular now. Coastal redwood (diff species) were much less widely planted. Definitely an interesting place to plant one tho!

no quite, I get that - I'm more wondering about why they are so popular despite little/no evidence as to the ecological benefits - that's always intrigued me. Charismatic microflora?

interesting (I get asked this a lot too). The engagement aspect of the 'tiny' shouldn't be overlooked (see houses, vans etc) & possibly feels more manageable than other interventions. Combined with the 'golden shovel' effect (as per Eisenman et al) it's a heady mix!
