Last week, we continued treating Carnation spurge (Euphorbia terracina) pictured at right. The seed of this invasive perennial germinates and continues growing over a period of many months. This year the number of new plants seems worse than usual. Let's hope that the extensive efforts we've been putting into controlling it put a significant dent in the seed bank.

Below is a photo of non-native Canarian sea lavender (Limonium perezii) at Lusardi Creek not far from Camino del Sur. This species is not described as invasive in California, though it is said to be abundant along our coasts and roadsides (https://naturecollective.org/plant-guide/details/perezs-sea-lavender-non-indigenous/). This is the only example of L. perezii we have seen in our work area. However we have come across other, superficially similar Limonium species that really are highly invasive (https://naturecollective.org/plant-guide/details/california-sea-lavender/).
