I really enjoy fragrant plants, and grew Brunfelsia “Yesterday, Today and Tomorrow” bushes back when I lived in the San Francisco Bay Area. Some Brunfelsia varieties require a more tropical climate, so check out your local area nurseries to find / get advice about which of the 40 or so varieties are best suited for your climate. There are tempting less-common Brunfelsia varieties that require a more tropical climate, but the ones I bought online mail-order to try growing in northern California did not grow well for me.
I now live in seasonally dry Kona where my small Brunfelsia bushes require recurring irrigation – if left too long without water I find they quickly drop their leaves and must be watered to bring them back to health. Those who live in drier areas on the mainland will likely need to provide irrigation.
Be sure to plant your Brunfelsia bushes near a window so you can enjoy their fragrance.
