IMO, a soil that is 50% peat/compost is going to be very heavy/water retentive & especially difficult to implement an effective watering program for, especially when the planting is immature & roots have not fully colonized the soil mass, so that would eliminate #3 for me. In #2, the mushroom compost will break down quickly & be hot (lots of urea), as well as high in soluble salts, but it's only 1/12 of the mix, so not the end of the world. I would really prefer no topsoil in my containers, and even though the topsoil is only 1/6 of the mix, the compost + topsoil = 25% of the soil in very fine particulates - it's going to hold lots of water. I'm guessing that if I was amending the #2 mix, I would probably mix something like 5 parts of #2 1 - 2 parts of fine bark 1/2 - 1 part of pumice Take a look at the #2 mix & see what you think. Amend if you think it needs it & disregard my thoughts if you think it doesn't. Regardless of what you decide, pay close attention to the consistency of the soil over time & whether or not you have water retention issues (as in too much if you don't amend, or possibly too little to suit you if you do). This will REALLY help you decide what direction to take next year - especially if you decide to use the same soil. Al

Looks like a Chicory. A winter salad ingredient.

I'm going to contact houzz with a recommendation (surely to be ignored) about making some kind of reminder appear for new posters, saying they should state their part of the country. Far too much time is wasted dealing with that, each time a n00b comes along. Back in 2008 I was asked to help someone create a lawn care forum. The very first contribution I made was to have a mandatory field for registration asking where they live. There are people who don't get it at first and put in "midwest" or something equally vague. Once we explain it to them, they all give us a city and state. The ones that get me say SoCal. Well...that reaches from Bakersfield to San Diego from Santa Barbara to Blythe. It goes from 50 feet below sea level to 10,000 feet with hills and mountains all over. Just saying SoCal is meaningless. Even saying Los Angeles is meaningless, because nobody really lives in Los Angeles. Santa Monica and Long beach are much different from Pasadena or Pomona.

Pasadena can be more than 10 degrees warmer in summer and waay dryer than Santa Monica or Venice or Playa del Rey. To people who don't live there it seems the same, but it is different. Since you use Sunset climate zones, Pasadena is 21, Coastal is 24. ZONE 21: Thermal belts in Southern California’s areas of occasional ocean influence The combination of weather influences described for Zone 20 applies to Zone 21 as well. Your garden can be in ocean air or a high fog one day and in a mass of interior air (perhaps a drying Santa Ana wind from the desert) the next day. Because temperatures rarely drop very far below 30°F (–1°C), this is fine citrus growing country. At the same time, Zone 21 is also the mildest zone that gets sufficient winter chilling for most forms of lilacs and certain other chill-loving plants. Extreme lows—the kind you see once every 10 or 20 years—in Zone 21 average 28 to 25°F (–2 to –4°C).All-time record lows in the zone were 27 to 17°F (–3 to –8°C). Coastal is 24 ZONE 24: Marine influence along the Southern California coast Stretched along Southern California’s beaches, this climate zone is almost completely dominated by the ocean. Where the beach runs along high cliffs or palisades, Zone 24 extends only to that barrier. But where hills are low or nonexistent, it runs inland several miles. This zone has a mild marine climate (milder than Northern California’s maritime Zone 17) because south of Point Conception, the Pacific is comparatively warm. The winters are mild, the summers cool, and the air seldom really dry. On many days in spring and early summer, the sun doesn’t break through the high overcast until afternoon. Tender perennials like geraniums and impatiens rarely go out of bloom here; spathiphyllums and pothos become outdoor plants; and tender palms are safe from killing frosts. In this climate, gardens that include such plants as ornamental figs, rubber trees, and scheffleras can become jungles. Zone 24 is coldest at the mouths of canyons that channel cold air down from the mountains on clear winter nights. Several such canyons between Laguna Beach and San Clemente are visible on the map. Numerous others touch the coast between San Clemente and the Mexican border. Partly because of the unusually low temperatures created by this canyon action, there is a broad range of winter lows in Zone 24. Winter lows average from 42°F (5°C) in Santa Barbara to 48°F (9°C) in San Diego. Extreme cold averages from 35° to 28°F (2 to –2°C), with all-time lows in the coldest stations at about 20°F (–6°C). The all-time high temperatures aren’t greatly significant in terms of plant growth. The average all-time high of weather stations in Zone 24 is 105°F (41°C). Record heat usually comes in early October, carried to the coast by Santa Ana winds. The wind’s power and dryness usually causes more problems than the heat itself—but you can ameliorate scorching with frequent sprinkling. https://www.sunset.com/garden/climate-zones/sunset-climate-zone-los-angeles-area
